摘要

近年来，大量新能源接入电网，其输出功率的随机性与波动性，在配电网中引发了严重的电压质量问题。电力电子变流设备因其补偿精度高，控制灵活等特点，已成为电压质量优化提升领域的研究热点。本文提出了一种新型的光储复合变流器拓扑及其电网电压支撑控制策略。所提拓扑由原边侧复合交错并联双向Buck/Boost电路的双有源桥电路与三相并网逆变电路拼接而成，其三端口可分别实现光伏阵列、蓄电池储能以及电网的接入，具有六种工作模式实现灵活的功率调度。所提电网电压支撑控制策略基于PCC点的电压反馈，在抑制PCC点电压波动的同时，具有补偿电流最小的效果。最后通过仿真分析验证了所提拓扑与控制策略的可行性。

Abstract

The randomness and fluctuation of the output power of a large number of new energy sources connected to the power grid can cause serious voltage quality problems in the distribution network. In recent years

power electronic converters have become a research hotspot in the field of voltage quality optimization and improvement due to their high compensation accuracy and flexible control. This article proposes a novel topology and voltage support control strategy for a photovoltaic energy storage composite inverter. The proposed topology is composed of a dual active bridge circuit of a primary side composite interleaved parallel bidirectional Buck/Boost circuit and a three-phase grid connected inverter circuit. Its three ports can respectively realize the connection of photovoltaic arrays

battery energy storage

and power grid

and have six working modes to achieve flexible power scheduling. The proposed voltage support control strategy is based on voltage feedback at the PCC point

which has the effect of minimizing compensation current while suppressing voltage fluctuations at the PCC point. Finally

the feasibility of the proposed topology and control strategy was verified through simulation analysis.
